Question 1

Click on the calculator icon in the upper left corner. A new Oracle database is being deployed on a 4-engine VMAX array. The DBA requests 2TB of usable capacity.
Which configuration will best distribute database workload across the back-end Disk Adapters (DAs) while avoiding host queing?

A.4 x 16-way meta devices using 32GB members
B.5 x 400GB devices
C.2 x 4-way meta devices using 50GB members
D.1 x 24-way meta device using 100GB members

Question 2

You are designing a Symmetrix VMAX array with 15K rpm Fibre Channel drives and 7.2K rpm SATA drives. How can you ensure that every back-end director manages just one type of drive?

A.Connect drives of just one type to each engine
B.Load drives of just one type in each bay
C.Load drives of just one type in each disk array enclosure
D.Connect drives of just one type to each front-end director

Question 3

Which database workload is suitable for EFD configuration?

A.Oracle Online redo logs and archive log file
B.Database objects with random read workload
C.Database objects with pure sequential workload
D.DSS database with high sequential write activity

Question 4

A data warehouse team is reporting poor performance on their batch reports. The database runs on a Solaris host connected to a DMX-4 array with Fibre Channel drives sized to support a sequential read workload. Which metrics in Performance Manager would be useful in diagnosing the performance issue?

A.Average sampled read time, KBytes read per second, I/O per second, Read hit %
B.KBytes read per second, Prefetched tracks per second, Read %, Write %
C.I/O per second, KBytes read per second, prefetched tracks per second, Tracks not used per second
D.Read hit %, Tracks not used per second, Average sampled read time, I/O per second

Question 5

During a Symmetrix VMAX performance analysis, you notice that a collection of VMAX devices has front-end I/O rates that are much higher than the back-end I/O rates. What might be the reason for this?

A.Workload has a high percentage of read hits.
B.Devices are replicated with TimeFinder/Clone
C.Devices are RAID 5 protected.
D.Workload has a high percentage of writes.
